Req 9 — Single Trestle Bridge
9.
Working in a group, (or individually with the help of your counselor) build a full size pioneering structure, using one of the following designs in the Pioneering merit badge pamphlet:Carefully plan the project, assembling and organizing all the materials, referring to the points under Safe Pioneering, and complying with the height restrictions in the Guide to Safe Scouting.
Single Trestle Bridge
This option is a natural extension of Req 8 because the trestle is the star of the project. If you liked tracing load paths and talking about braces, this is one of the best capstone builds in the badge.
